The thin layer of skin between a woman's inner vagina and inner anus. You can achieve this by placing your penis in either the vagina or anus, then put your finger in the opposite hole then feel around for the penis outline on the Shigina. Good Luck :)

Shigina is a term used for when a man takes a shit in a woman's vagina. This is used when having sex. A man places his asshole on the girls vagina and takes a shit.
